AKD4122A-A
Evaluation board Rev.0 for AK4122A
GENERAL DESCRIPTION
The AKD4122A-A is an evaluation board for the digital sample rate converter, the AK4122A with built-in
digital audio interface receiver (DIR). The AKD4122A-A has the digital audio interface and can achieve
the interface with digital audio system via opt-connector.

„ Operation sequence
1) Set up the power supply lines.
[AVDD]
(red)
= 3.0 ∼ 3.6V (typ. 3.3V, AVDD pin)
[DVDD]
(red)
= 3.0 ∼ 3.6V (typ. 3.3V, DVDD pin)
[+5V]
(orange)
= +5V (for regulator)
[VCC]
(blue)
= 3.0 ∼ 3.6V (typ. 3.3V, for digital logic)
[AGND]
(black)
= 0V
[DGND]
(black)
= 0V
Each supply line should be distributed from the power supply unit.
2) Set up the evaluation mode, jumper pins. (See the followings.)
3) Power on.
The AK4122A should be reset once bringing SW6 (PDN) “L” upon power-up.
„ Evaluation mode
I/O ports and jumper pins on the board should be set according to the following explanation in order to evaluate each
pass of the AK4122A. The block diagram is shown in Figure 2.

Refer to page 5 ∼ 10 for input port setting, and output port setting should be master mode. The bypass mode of the
AK4122A is set by the register.
In bypass mode, the DIT function of the AK4114 can not be used as the output port. 10pin PORT should be used
instead.
Input BICK, LRCK, and DATA are output from the output port side in the bypass mode.
